As for your request, this plugin is only a parser for oEmbed and other WP embed providers.

I’m looking at creating another plugin to extend video support to other sites like Tudou. Though, I should note that I will not be getting to this any time soon. If you need this immediately, I’m available for plugin customization.

If you’re looking at adding support for Tudou manually, it looks like Tudou doesn’t support oEmbed, so you’ll need to add it as an embed provider.
